Specification of Letters Patent. Application filed November 3, 1909. Serial No. 526,099.

To all whom it may concern."

Be it known that 1, JOHN J. ROBINSON,- a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Stretchin -Frames, of which the following is a speci cation.

This invention relates to curtain stretchers and its object is to provide a stretcher of simple construction to provide for ourtains of any size or several curtains of different sizes which may be put upon the frame and stretched and dried on both sides, as will be more fully described in the following specification, set forth in the claim and illustrated in the drawings, wherein:

Figure 1 is a perspective view of the 1 varioussizes, of internnsslons which may exist within the horizontal bars and on the Stretching frame. Fig. 2. is 'an elevation of the same from the opposite side. Fig. 3 is a detail perspective view of one of the filling pieces. Fig. 4c is a cross sectional view of the frame on. the line 4:4 of Fig. 2. Fig. 5

tains to be stretched, filling pieces 14 are set upon the reduced parts '11 of the cross bars is a perspective view of a filling piece for one side of the frame.

The frame is made up of the longitudinal bars '5 practically identical in shape and len th and having at one end the tongues 6 win e the opposite ends are slotted as at 7. These bars are connected by the cross bars 8 with a slot 9 to receive the tongues 6while at the other end of the stretcher is provided a cross bar 10 having a reduced portion 11 over which fits the forked ends of the bars 5 and to which they are attached by means of the pins 12. The bars 8 and 10 are provided with perforations 13 through which the pins 12 pass to connect the longitudinal and the cross bars and they are adjusted with relation to each other by the insertion of the pins at the proper points. When the two sets of bars are properly adjusted to the necessary sizes for the curso that the whole' frame may present a flushed surface all around to properly support the curtain which is being stretched.

The curtain while being stretched is secured to the frame by means of pins 15 which will be seen in Fig. 1 to occupy theinner edge of the entire outer. frame and thus provide for a curtain of the largest possible dimensions for the frame but when It is necessary to stretch a smaller curtain they are secured to the other side of the frame as shown in Fig. 2 where will be seen frames A, B, C and D for curtains of various dimensions, the curtains C and D being especially adapted to transoms or the panes of the front doors of buildings and around the edges of these various frames are arranged the pins 15 upon which the curtains are secured.

Fig. 4 shows a cross section of one, of the bars of the frame where it will be seen that the inner edges are beveled so that the pins 15 are lower than the sides 16 of the main portion of the frame.

The filling pieces 14 are provided for cross pieces. It is obvious that the number of bars'is' not limited to the{ number shown in'the drawings but may be increased in number as the occasion may demand and various other modifications may be made in the details of the frame without departing from the essential features above described.

A frame constructed in accordance with this invention may thus be utilized to stretch curtains or similar objects on each side at the same time, no matter whether the curtains are the same dimensions or whether a large curtain is held by one side of the frame and the other side carries a smaller.-

curtain or several smaller curtains on its various frames. As will be seen the bars of the frame are readily adjustable for the reception of various sized curtains and although a large curtain may occupy the outer bars the inner bars may be adjusted to hold p) smaller curtains on the other side of the frame.

' What I claiin as new and desire to secure by Letters Patent is: In a stretching frame, the combination with outer longitudinal bars ,slotted at one end and having a tongue at the other end, of a similar-auxiliary bar adapted to be located between the outer bars, a slotted cross bar at one end of the frame adapted to receive the tongues at the ends of the longitudinal bars an outer cross bar with reduced portions to fi t within the slots of the lonenter perforations in the bars to enlarge or In testimony whereof I afix my signature in presence of two Witnesses.

stretched, and connecting pins adapted to redilce the sizes of the frames.
